title: Physical inactivity at leisure and work: a 12-month study of cardiac patients.
abstract: OBJECTIVE
  Physical inactivity has been identified as a distinct health risk. However, little is known about how this can vary at leisure and work in cardiac patients. The aim of this study was to examine the prevalence and predictors of inactivity during leisure and work in the 12 months following a cardiac event in Australian cardiac patients.
  
  
  METHODS
  A total of 346 patients consecutively admitted to hospital with acute coronary syndrome or to undergo coronary artery bypass graft surgery were interviewed in hospital, and 4 and 12 months later. Leisure and occupational physical activity was measured using the Stanford Brief Activity Survey. Sociodemographic, psychosocial, and clinical data were also collected.
  
  
  RESULTS
  The prevalence of leisure-time physical inactivity declined over time, with 52% inactive preevent and 29% inactive at 12 months. Approximately 50% of participants were physically inactive in their work, regardless of whether this was measured before or after the cardiac event. Logistic regression revealed that the significant predictors of leisure-time physical inactivity at 12 months were non-home ownership (OR = 2.19; P = .007) and physical inactivity in leisure-time prior to the event (OR = 2.44; P = .001). The significant predictors of occupational physical inactivity at 12 months were white-collar occupation (OR = 3.10; P < .001) and physical inactivity at work prior to the event (OR = 12.99; P < .001).
  
  
  CONCLUSIONS
  Preevent physical inactivity, socioeconomic, and clinical factors predicted both leisure and work inactivity after an acute cardiac event. Effective interventions could be designed and implemented to target those most at risk of being physically inactive at work or leisure.
